The former Bolingbrook police sergeant suspected in his fourth wife’s Oct. 28 disappearance said Thursday he’s prepared for an arrest and even a lengthy prison sentence.

“I’m prepared for anything that could come up,” Drew Peterson told NBC’s “Today” show host Matt Lauer. “My main concern about anything is for my children, and once all my ducks are in line for their well-being, I’m OK.”

The interview, Peterson’s third on “Today,” came the day after he and his attorneys won a three-month court battle to force the state to return to Peterson several seized items, including 11 guns, two vehicles and computers. The victory was short-lived, however, as the Will County state’s attorney announced later Wednesday that state police had revoked Peterson’s right to legally possess a firearm in Illinois.

Will County State’s Attorney James Glasgow sent a letter Tuesday to State Police Director Larry G. Trent requesting he revoke Peterson’s firearm owner’s identification card. State police sent a letter to Peterson Wednesday informing him of the decision.

News of the revocation came just hours after Will County judge Richard Schoenstedt ordered the state to return the items seized while police carried out their Nov. 1 search warrant.

In his ruling, Schoenstedt said Peterson must maintain a valid FOID card to keep the guns.

Officials did not specify why Peterson’s FOID card was revoked or on what grounds, but a card may be revoked for a number of reasons, according to state police. Fugitives, suspects under indictment for a felony, convicted felons, drug users and recent mental institution patients are all ineligible to carry a FOID card under state law.

Officials will return the other seized items within a month, provided Peterson appears in court March 17 and agrees to a set of conditions, which include an agreement to not dispose of the items and, in the event the case goes to trial, an agreement to not challenge the validity of photographs or other renditions of the property during the trial.

Peterson’s attorney, Joel Brodsky, had argued for months that investigators have had enough time to conduct all necessary forensic testing on the possible evidence and has said investigators were keeping the items solely to frustrate his client.

Chuck Pelkie, spokesman for the Will County state’s attorney, called the ruling reasonable and said all forensics testing had been completed or will be completed “in the near future.”

Peterson is a suspect in his wife Stacy’s disappearance, which investigators are calling a possible homicide.

A grand jury has been meeting for months to investigate Stacy Peterson’s disappearance and the March 2004 drowning death of Drew Peterson’s third wife, Kathleen Savio.

Savio’s body was found in an empty bathtub in her Bolingbrook home. A six-person coroner’s jury ruled the cause of death as an accidental drowning, but the case was reopened shortly after Stacy Peterson went missing.

Savio’s body was exhumed in November, and an independent forensic pathologist for the state ruled her death a homicide Feb. 21.

Peterson and his lawyer, Joel Brodsky, fielded a round of tough questions from Lauer during Thursday’s interview, which marked the four-month anniversary of Stacy Peterson’s disappearance.

“People watching Drew are thinking one of two things, either you are experiencing the worst string of luck in the history of the world, or that you are involved deeper in this than you’re letting on,” Lauer told Peterson.

Both Stacy Peterson and Savio had told loved ones that Drew Peterson was controlling and abusive.

“I controlled my family,” Peterson said. “I think more people in America should control their family.”

But Peterson denied any wrongdoing in either case and said he still believes Stacy left him for another man and that Savio’s drowning was an accident.

Attorneys for Peterson’s and Savio’s families will be in court March 17 for a hearing on the family’s petition to have Savio’s estate reopened.

The petition is the first step in the process of filing a wrongful death lawsuit against Peterson on behalf of Savio’s estate.
